摘　　要：作为雾霾的主要成分,PM2.5越来越受到人们的重视,但传统的PM2.5环境检测仪造价昂贵,使用不方便,难以在家庭中应用。基于此,基于传感器技术和STM32设计了一款智能家用PM2.5环境检测仪。使用夏普GP2Y1010传感器完成对粉尘颗粒物的采集,温湿度传感器DHT11完成室内温湿度的采集,AD转换转换之后送入STM32单片机进行控制处理,并在OLED显示屏上进行显示,同时可以设置超限报警值,当PM2.5浓度超过设定值之后,进行声光报警和GSM模块发送短信提醒。As the main component of fog and haze, PM2.5 has been paid more and more attention, but the traditional PM2.5 environment detector is expensive and inconvenient and difficult to use in the home. Based on this, a intelligent home PM2.5 environment detector has designed based on sensor technology and STM32. Using the SHARP GP2Y1010 sensor of dust particles collection, temperature and humidity sensor DHTl I to complete the indoor temperature and humidity acquisition, afterAD conversion into STM32 MCU control processing, and displayed on the OLED screen, and can set the alarm value, when the PM2.5 concentration exceeds the set value, the acousto-optic alarm and GSM module SMS alerts.
